Answer:
26 feet
Step-by-step explanation:
w: width
w+4 : length
w(w+4) = 572
w² + 4w - 572 = 0
w² + 26w - 22w - 572 = 0
w(w+26) - 22(w+26) = 0
(w-22)(w+26) = 0
w = 22, -26
width = 22 feet
length = w+4 = 22+4 = 26 feet
Answer:
x = 12.75
Measure of angle YXZ = 49.75 degrees
Step-by-step explanation:
<em>Complementary angles have a sum of </em><em>90</em><em> degrees so we </em><em>add </em><em>them and set them equal to </em><em>90.</em>
3x + 2 + 5x - 14 = 90
<em>Combine like terms</em>
8x - 12 = 90
<em>Add </em><em>12</em><em> to both sides</em>
8x = 102
<em>Divide both sides by </em><em>8</em><em> to isolate </em><em>x</em>
x = 12.75
Measure of angle YXZ = 49.75 degrees
